JBOSS EAP6.4中的NoClassDefFoundError

Question

當我在JBOSS EAP6.4中部署我的戰爭時，盡管我的類路徑中有jackson-mapper-asl.1.9.2.jar並且設置為讀取部署結構，但我得到以下錯誤

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="deploy" />
            <module name="org.codehaus.jackson.jackson-mapper-asl" />
        </dependencies>
    </deployment>
</jboss-deployment-structure>

下面是日志堆棧

怎么解決這個？

Answer 1

看起來“deploy”文件夾可能不位於模塊下正確的文件夾樹級別。 我還建議不要將其命名為“deploy”文件夾，以避免與實際部署混淆。

您的文件夾結構應該如下所示，如果您想讓它在引用時工作。

vend/hybris/jboss/jboss-eap-6.4/modules/deploy/main 。 在此文件夾下，您應該有一個module.xml文件以及對必要的jar以及jar本身的引用。

Answer 2

我已經通過將jar添加到我的部署模塊來解決了這個問題。 看看是否有另一種方法來解決問題，截至目前，將jar添加到部署模塊已經解決了這個問題。
